We look at the division of 278749 by 2 
Our goal is to divide 278749 by 2.

On to step 1:
2 can be fit into 2 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 2 from 2 and we're left with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 2

Let's proceed to step 2:
7 divided by 2 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 6 from 7, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 2

Moving on to step 3:
2 can be fit into 18 9 times, resulting in a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 139.0
Deduct 18 from 18 and we're left with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 2

Going ahead to step 4:
7 divided by 2 is 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 1393.0
Deduct 6 from 7 and we're left with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 2

On to step 5:
If we divide 14 by 2, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 13937.0
Subtract 14 from 14 to get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 2

Step 6:
The number 2 fits into 9 4 times, leaving a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 139374.0
The remainder is 1 after subtracting 8 from 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 139374.5
If we subtract 10 from 10, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 139374.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 139374.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 139374.5, and the remainder is 0.0.
